SAW-HANDLE.

Specification of Letters Patent.

Patented Nov. 13, 1906.-

Appiimion ned Maly 6,1905. serial No. 259,172.

To all whom t may concern:

Be it known that I, MICHAEL H. TooMEY, a citizen of the UnitedStates,residing at Glenhazel, in the county of Elks and State of Pennsylvania,have invented a new and useful Saw-Handle, of Which the following is aspecification.

This invention relates generally to saW- handles, and particularly toone of that class of handles that are employed in connection withcrosscut-saws driven by two operators.

The object of the invention is to provide a novel form of fastener whichshall be positive in holding the saw-blade against loosening orseparation therefrom, and in Which disconnection of the handle from thesaw will readily be effected when desired.

Vith the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a saw-handle, as will behereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which like characters of reference indicate corresponding parts,Figure 1 is a view in elevation eX- hibiting the handle of the presentinvention combined with a portion of the saw. Fig. 2 is a view inelevation, partly in section, showing more particularly the interiorconstruction of the saw blade locking mechanism. Fig3 is a perspectivedetail View of a slightlymodified form of saw-engaging shank. Fig. 4 isa perspective detail view, partly in section, of the socket.

The implement of the present invention embodies a handhold l, of theusual or any preferred construction, a socket 2, and a splitsaw-engaging shank 3.

The socket 2 is provided at one end with one of the shank-lockingmembers, the same consisting of an annular inclined end or locking-face4. The other locking member 5 is carried by the shank 3, and has avolute cam-locking face 6, which coacts with the like face of thelocking member 4 to effect longitudinal draft upon the shank to cause itto bind the saw S against the outer end of head of the socket. Thelocking member 4 is, by preference, integral with the socket, although,if preferred,it maybe made as a separate element and secured thereto.

In the form of the invention shown in Fig. 2 the locking member 5 isintegral with the shank 3, but in the form of the invention shown inFig. 3 the locking member 5 is provided With a threaded orifice, whichis engaged by the threaded stem 8 of the shank, the projecting end ofthe stem being upset or headed to prevent separation of the tWo membersin use.

The shank 3 maybe made of any suitable material, preferably of malleablecast-iron, with which in the form of the invention shown in Fig. 2 thelocking member is cast integral and is provided with a longitudinalorifice or slot 9 to receive the terminal of the saw, as clearly shownin Fig. 2. The slot 9 will in practice be made of sufficient length toreceive saw-blades of different widths, thereby to extend the range ofutility of the implement. Instead of having the shank cast, as shown inFigs. 2 and 3, it may be constructed of a piece of metal bent uponitself, the deiiected members being s aced apart a sufficient distanceto form a s ot to receive the blade.

The lower end of the handhold, as usual, is reduced to fit in thesocket, thus to obviate the presentation of ashoulder or projection atthe point of juncture of the parts, and to prevent accidental separationthereof a rivet or pin 10 may be passed through suitable orifices in thesocket and through the reduced end of the handhold. (Shown in Fig. 2.)

In the use of the implement the saw is inserted through the slot 9 ofthe shank, and the handle 1 is gras ed in one hand, and the free end ofthe shan is pressed against the other hand or against some fixed object.As a result the socket 2 will be slid longitudinally upon the shankuntil it comes in contact with the saw. The handle l can then be rotatedpractically without friction until the annular inclined end face thereofcomes into contact with the corresponding face of the member 5,whereupon the socket end will be caused to bind tightly a ainst the saw.The adjustment of the shan and socket against the edges of the sawisthus greatly facilitated and said parts can be caused to bind upon thesaw by making less than one rotation on the socket. When thelocking-faces are tightly wedged together, they will be positive inholding the shank against loosening, thereby effecting a stable juncturebetween the handle and the saw. To remove the saw, it will only benecessary to turn the handhold in the opposite direction to that turnedin tightening the shank, whereupon the coac.

IOO

IIO

tion between the locking-faces Will cause the shank to be projectedbeyond the socket, and thus release the blade.

The construction herein shown, While eX- ceedingly simple, will be foundthoroughly effective in use for the purposes designed, and will in apositive manner hold the blade against any tendency to Work loose-or toWabble Within the clamp.

Having thus described the invention, What is claimed is 1. A saw-handleembodying a socket provided at one end With an annular inclined endconstituting a locking-face, and a longitudinally-slotted saw-engagingshank carrying a head adapted to fit snugly Within the socket andprovided With an annular inclined end locking-face to coact with that ofthe socket said'shank and its head being slidable longitudinally Withinthe socket to facilitate the adjustment.

2. A saw-handle embodying a socket provided at one end With an annularinclined end constituting a lockingface, and a longitudinally-slottedsaw-engagingr shank carrying a detachable head adapted to fit snuglyWithin the socket and provided With an annular inclined locking-face tocoact with that of the socket said shank and its head being slidablelongitudinally Within the socket to facilitate the adjustment.

3. A saw-handle comprising a socket having an annular inclined endconstituting a locking-face, a longitudinally-slotted sawengaging shankslidable longitudinally Within the socket and carrying a head providedWith an annular inclined end constituting a locking-face, said facesadapted to coact subsequent to the longitudinal movement of the shankWithin the socket.

In testimony that I claim the foregoing as my own I have hereto afliXedmy signature in the presence of tWo Witnesses.
